Chucking oil out the back?

[CM2005]

does your KDX run pre mix then?? mine was a jap import?? and ran with an oil tank autolube system.

[theblacksmith]

whats a kdx ment to run standard. I thought it was 32:1, but maybe someone could check in a manual.

I run mine on 32-1 -after asking the nice staff at Hamilton Motorcycles(Kawasaki)
They reckon all Kawasaki 2T should be run on 32-1.
Never had any problems - just cleaned my expansion chamber out(by cutting through weld and scraping it all out and rewelding) it was sooty carbon and no oily shit.
However the deposits in the rear muffler are a wee bit oilier(cooler environment i suppose),Im happy with the way she goes.

Mine has a pump for autolube-I think the last owner must have scrapped the oil tank - Ive always used pre-mix since Ive had the bike.

ANYHOOO----- I ripped the packing outa the muffler. Hmm enuff oil to run a car for a week in there. remove the whole zorst -tipped it up and glugg glugg etc.
Threw a new plug in her and bolted all back together again
Half a tank of 40/1 and lets see what happens.
First off still smokey/oily. . Then got her fairly hot with use of high rpm
Well ferk me now we have normal two stroke smoke
That all done and feeling pretty smug was I
A young guy rocks up to the yard and makes an offer to buy I couldn't refuse. He reckoned his dad was a bike spanner man so no worries.
Next thing I get a call from daddyo-Oyy what didya do to this thing??
Hu says I --Daddyo then tells me it goes like a friggin raped ape.
Trouble is not I got no friggin bike AGAIN
Anyone got a trailee for sale???

i hate oil pumps my old 91 kdx250 use an oil pump and it stopped working resulting in a siezed motorbike. i have to my muffler packing soon its starting to sound a bit muffled.

Pre mixing does give some peace of mind aye.

theres alway a human element needed to keep machines running. theres no way to tell if the pump is working properly with out taking half the bike apart. but yea i wouldnt not use pre-mix

Sure dose was the first thing i threw out on my jet ski when i had it last thing you would ever want was a oil pump that gave up the go while out in the harbour.

Hmmm, interesting thread.
I've recently got my hands on a 2006 KDX200 and I've fouled two plugs now. Running 40:1 with one heat range hotter plug.

My exhaust has nice oil drips running out the end.... Its possible that I've got the same problem. Might take the pipe off and try the petrol trick.
Its not really smoky while riding either. Just typical 2t smoke.

Plug fouled today after starting it up with the choke on. After about 20sec of revs I removed the choke and rev'ed it a couple of times. Then I left it idling for a couple of mins while faffing around with gear etc. I then rode to sign in for the ride. So far so good...

Went about 100m into a trail and ended up getting off to help some poor kid on a quad up a sandy hill. Once he was sussed I launched my bike up and then it all went to shit. Wouldn't idle etc. I could hear it missing. Giving it more throttle didn't do anything, just more missing etc.

So I ended up changing the plug there and continuing on my way. Pisser-offer though.

Should I not let it idle for minutes at a time while cold? I would love to know if I'm doing something fundamentally wrong. The rest of the ride was sweet, no problems, went really good.

I've only had a 4t before this. Is there some sort of special 2t ritual that I don't know about. Note: both times I've fouled a plug has been when starting a ride at the begining of a trail ride. Once its warm its sweet.

Why is this always so hard? You need to sort your jetting out, its too rich.

First try setting your air screw, back it out an 1/8 of a turn at a time but generally don't go past 2 1/2 turns out and listen for a lean rattle or high idle and come back if you go too far. Its possible the pilot jet is too rich. Off course a two stroke should be able to warm up and idle as normal if jetted correctly.
There have been so many posts about jetting just this year and if you can't use the search function, later on today I will search them out and post all the links. Even the content of this thread should tell you that you need to sort out your jetting. Its only going to get worse with the warmer weather.
I think we need a jetting sticky in the off road section to guide all these people towards.

Here you go read this thread http://www.kiwibiker.co.nz/forums/sh...32#post1630932 and on the first page there are links to a further 3 threads regarding jetting from earlier this year. Lots to read but some good info and should hopefully set you on the right track (once you sort the wheat from the chaff lol).

Cheers Danger. I figured it wouldn't be the jetting as its a fairly new bike and 'should just work' from the factory? It has a pro-circuit pipe which I guess could screw things up a bit?

Of course I'm assuming that the previous owner didn't fiddle with it at all. Another interesting point is that when I first got the bike it wouldn't idle unless you gave it a little bit of throttle. So I adjusted the idle which I'm assuming is the air screw you mention. Maybe this wasn't such a good idea.

Forgive my 2t ignorance. :P

[Danger]

No the idle screw and air screw are seperate.
As the weather gets warmer your bike will run richer so you need to adjust the air screw (and perhaps other jets) leaner.
Most bikes come jetted too rich for safety.
As the weather gets cooler your bike runs leaner, so you need to richen it.
On all my two strokes I have both a winter set of jets and a summer set of jets.
The air screw might need adjusting daily for changes in temp and humidity.
